Very Early Pro Sound - Field Coils with Horns and Triodes 245 250

This is one of my favorite early ads because it has it all like field coils, horns, triodes in the flavor of 250 and 245.

$20 in 1930 equals about $275 today.

 Nice selection of field coils from the early guys Jensen and Utah.

 I want everything I build to look like these early pro amps.
